Edward Jenner administered the world’s first vaccination as a preventive treatment for smallpox. He took fluid from a cowpox blister, attenuated the cowpox virus and introduced it into the skin of James Phipps, an eight-year-old boy who is suffering from smallpox. A single blister rose up on the spot, but James soon recovered.

So, the correct answer is 'Attenuated cow's pox virus'.

A vaccine typically contains an agent that resembles a disease-causing microorganism and is often made from weakened or killed forms of the microbe. The agent stimulates the body's immune system to recognize the agent as a threat, destroy it, and to further recognize and destroy any of the microorganisms associated with that agent that it may encounter in the future.
